Climate reanalysis shows these far above average temperatures extending well into April. And, as a result, the Arctic chill that typically settles over this often-frozen region has been greatly reduced throughout winter and on into early spring.

2017 marks the 4th consecutive year of excessive winter warmth for this section of our world. A human-emissions-driven rise of abnormal heat that brings with it consistently earlier thaws, disruptive permafrost melt, and the freeing of new, deep-running, peat-like fuels for wildfires. A fuel that can smolder on through winter to again mar the land with new surface fires once the thin covering of snow draws back. An event that is occurring earlier and earlier as the decades and the great outpourings of oil, gas, and coal based carbon into the atmosphere wear on.

By Sunday, the fires sparking closer to Lake Baikal further east had also grown their own series of tell-tale smoke plumes. One particular blaze in central Siberia appeared to have produced a 2.5 x 6 mile long burn scar in just one day (about 10,000 acres).

This year’s early wildfire eruption in Siberia comes after 2014, 2015, and 2016 wildfire outbreaks during similar timeframes and following similarly abnormal warm periods. These fires tended to crop up south of Lake Baikal or closer to the China-Russia border. This year, the early fire outbreak appears to have emerged both further north and generally along a wider expanse than during past years.

If past years are any guide, we can expect the present fire season’s early start to produce blazes that continue through September and that peak sometime during late June through August. The fires will tend to be very large and will probably range as far north as the Arctic Ocean.

(By summer, wildfires in Siberia are now capable of repeatedly producing massive smoke plumes like this 2,500 mile long monstrosity that was visible from 1 million miles away in space during a 2014 event. Image source: LANCE MODIS.)

These fires will gain ignition from new Arctic thunderstorms. They will be fed by new fuels such as thawing permafrost and trees harmed by northward invading species or by climates warming at rates far faster than they can handle. And they will be capable of casting off gigantic smoke plumes that encircle the higher latitude reaches of the globe.

Instances of this kind are the upshot of new climate change related impacts. We wouldn’t have expected such a vast amount of Arctic and near Arctic burning over a 5 month fire season during the 19th or 20th Centuries. But the new very large cold-region fire outbreaks are happening in a world at around 1.2 C hotter than 1880s averages and warming. And, unfortunately, if we keep warming, we can expect a considerable worsening of these already troubling events.
